Jose Mourinho has taken a swipe at Roma owner Dan Friedkin.

Mourinho was sacked by Friedkin last month and replaced by Daniele De Rossi.

Speaking as an ambassador for Football.com, Mourinho said: "The European competitions are about to begin, in particular the Champions League, perhaps the most important competition on the world calendar.

"I won't be there at these final phases, not because I have already been eliminated, but because I was 'eliminated' by someone who knows little about football.

"That's life, full of ups and downs, and I'm growing, despite the unexpected and unfair dismissal.

"But I'll be back, and with even more enthusiasm and confidence, for these UEFA matches."
